Concealed Mounting Assembly for Stable Lightweight Panel Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements for lightweight panels on walls often result in unintended movement due to weight-induced moments, leading to potential detachment and poor load capacity, especially when visually concealed fittings are required.
Innovation Solution
A fastening arrangement featuring a holding part with a first section integrated into the lightweight panel and a second section that interacts with a support fitting in a latching manner, providing a locking connection that prevents sliding and enhances load transfer to the wall, using a design with a first section extending further and a wider second section for improved stability and moment absorption.

Engineering Contradiction Analysis
1Shape
If a lightweight panel with integrated holding part is used, then the visual appearance is improved (concealed fittings), but the load capacity and stability deteriorate due to poor force introduction
Solution Approach 1:
The holding part is divided into two functional sections: a first section that extends into the lightweight panel for integration, and a second section that interacts with the support fitting in a latching manner. This segmentation allows the holding part to simultaneously achieve concealed mounting (visual improvement) and secure mechanical connection (load capacity maintenance).
Solution Approach 2:
The holding part extends in the direction of extension (perpendicular to the wall) with the first section penetrating into the panel depth, creating a three-dimensional integration that strengthens the connection without compromising the flat visual appearance from the front.
2Ease of operation
If the holding part is pushed axially onto the support fitting, then the mounting process is simplified, but unintended movement and detachment occur due to weight-induced moments
Solution Approach 1:
The latching connection is designed to automatically engage when the holding part is pushed onto the support fitting, creating a preliminary locking action that prevents subsequent unintended movement and detachment caused by weight-induced moments during normal use.
Solution Approach 2:
The latching mechanism provides a dynamic connection that allows initial axial insertion for simple mounting, then transitions to a locked state that resists rotational and lateral movements, adapting to the different mechanical demands during installation versus service.

AI summary
The arrangement (1) has a lightweight construction board (4) extending in an extending direction (X) from a rear narrow side (4.1) to a front narrow side (4.2). A holding part (8) is integrated into a middle layer (6) in the extending direction. An upper slab (5a) and a lower slab (5b) contact an upper side (8.1) and a lower side (8.2) of the holding part, respectively. The holding part cooperates with a supporting unit (7.2) of a support bracket (7). The middle layer is formed between the upper and lower slabs of the lightweight construction board.
